Vulnerability AssessmentAI
| Exploitation | The victim must be running a Google Chrome desktop release prior to 150.0.7871.47. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N) captures a remotely exploitable, low-complexity attack requiring only user interaction, with a high integrity impact but no scope change and no confidentiality or availability loss. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that triggers insufficient input validation in Chrome's DeviceBoundSessionCredentials component, causing the browser to make erroneous cross-origin trust decisions. When a user on a vulnerable Chrome version visits the page - via a phishing link, malicious ad, or compromised site - the SOP bypass allows the attacker's script to perform integrity-impacting cross-origin operations against the victim's browser session. … |
| Remediation | The primary remediation is to update Google Chrome to version 150.0.7871.47 or later, confirmed available via the Chrome stable channel release advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
